Release Timeline
February 6, 2026 launch follows Version 2.5 completion (started December 30, 2025). Creates 6-8 week preparation window during Ye Shunguang's Phase 2 banner (January 21 - February 17, 2026).
Phase 1 concludes ~February 27, 2026. Phase 2 extends into mid-March 2026.
Major Content Additions
Beyond Angels of Delusion, Version 2.6 confirms Sixth Street Area expansion—new explorable zone within New Eridu. Three simultaneous S-Rank agents indicates substantial story content, surpassing typical 1-2 agent updates.
Sixth Street Area: Complete Breakdown
First confirmed map expansion in 2.6 leaks. Based on naming conventions, Sixth Street likely connects to established districts through Inter-Knot fast travel, potentially commercial/residential zone.
Map Layout and Connections
Precise coordinates haven't leaked. Integration pattern suggests multiple entry points after prerequisite story missions, gradual sub-zone unlocking. Expected content density: 15-20 hidden collectibles, 5-8 new commission types based on previous expansions.
NPC Interactions and Commissions
New areas historically introduce faction-specific NPCs providing daily/weekly commissions. Angels of Delusion presence suggests Sixth Street features affiliated NPCs offering faction-specific materials. Commissions typically reward 20-40 Polychrome each—essential for F2P accumulation.
Hollow Zero Integration
May introduce new Hollow Zero entry points or specialized combat domains. Expansions typically add enemy configurations testing team flexibility, potentially favoring Nangong Yu's crowd control.
Exploration mechanics likely include verticality elements requiring specific movement abilities. Holographic theme suggests environmental puzzles involving light manipulation.
Predicted Collectibles
Expected content: 15-25 Observation Logs, 8-12 hidden chests, 3-5 rare collectibles unlocking achievements. Hidden secrets may include time-gated events, weather-dependent spawns, NPC interaction chains. Technological theme suggests ARG-style puzzles with holographic projections.
New Characters Leaked for 2.6
Angels of Delusion introduces three S-Rank agents addressing meta gaps:
Sunna (Ice Support)
On-field meter building triggers teamwide ATK/CRIT buffs
Universal applicability, maximized in Ice teams
Active playstyle vs. passive buff application
Aria (Ether Anomaly Main DPS)
Dual-form mechanics: robot form (defensive/energy) vs. human form (burst damage)
Stance-based combat requiring form-switching mastery
Addresses shortage of high-tier Ether damage dealers
Nangong Yu (Physical Stunner)
Holographic stage effects pull enemies together
Daze application + teamwide buffs during Chain Attacks
Improved crowd control for multi-target scenarios
Faction and Story Roles
Angels of Delusion suggests antagonistic/morally ambiguous organization. Holographic/tech themes indicate high-tech corporate or research background, possibly connected to Hollow investigation.
Three simultaneous releases typically involve major narrative arc spanning multiple chapters. Each character receives dedicated story missions rewarding 300-500 Polychrome total.
Signature W-Engine Compatibility
Each S-Rank releases with signature W-Engine:
Sunna: Energy Recharge/Support stats
Aria: Anomaly Proficiency/Ether DMG bonuses
Nangong Yu: Daze multipliers/Physical DMG amplification
W-Engine investment: 400,000 Dennies + components (Basic x4, Reinforced x32, Specialized x30) to reach Level 60.
Meta Shift Analysis
Version 2.6's three specialized agents create new team compositions addressing current limitations. Expands elemental coverage and tactical flexibility for endgame content.
Current 2.5 Meta
Centers around Zhao (Ice Defense, free event copy) and Ye Shunguang (Physical Attack). Meta favors mono-elemental teams maximizing elemental weakness exploitation. Ice/Physical compositions dominate Shiyu Defense clears.
Predicted Meta Shifts
Sunna: Universal support potentially replacing/complementing existing options. On-field meter building shifts support playstyles from passive to active rotation participation.
Aria: Addresses Ether damage dealer shortage, establishing Ether as viable endgame element. Dual-form mechanic introduces skill expression opportunities.
Nangong Yu: Crowd control specialization counters multi-target scenarios. Holographic stage pulling creates synergy with AoE damage dealers.
Team Composition Flexibility
Diverse role distribution (Support/Main DPS/Stunner) enables complete faction teams, though optimal compositions incorporate other factions. Sunna's universal buffs work beyond Ice teams. Nangong Yu provides alternatives to existing Stunners, reducing dependency on limited rosters.
Essential Pre-Farming Checklist for 2.5
Strategic pre-farming maximizes Version 2.6 readiness. S-Rank agents follow standardized material progression.
Buy ZZZ Monochrome recharge online through BitTopup to supplement Polychrome reserves for triple S-Rank rotation.
Priority 1: Agent Promotion Materials
S-Rank ascension (Level 0-60):
Role-specific Certification Seals: Basic x4, Advanced x32, Superior x30
800,000 Dennies
Sunna: Support Seals (Ruler superior)
Aria: Anomaly Seals
Nangong Yu: Stun Seals
Certification Seals drop from Combat Simulation role-specific stages. Each run costs Battery Charge, yields 2-4 seals. Full ascension requires ~15-20 completions per agent.
Priority 2: Skill Materials
Skill maximization per agent:
Basic Attribute Chips x25
Advanced x75
Specialized x250
Hamster Cage Passes x5
2,905,000 Dennies
Hamster Cage Passes drop from weekly bosses only. Version 2.5 provides 6-8 weeks = 30-40 passes total (enough for one agent's complete skills + partial upgrades).
Specialized Chips require ~40-50 simulation completions—most Battery Charge-intensive activity.
Priority 3: Dennies Accumulation
Combined cost per agent: 3,705,000 Dennies (ascension + skills). Three agents = 11+ million Dennies.
Optimal farming routes:
Daily commissions: 30,000-50,000/day
Hollow Zero: 100,000-200,000/weekly reset
Combat Simulation Denny stages: 15,000-25,000/run
Events: 50,000-500,000 variable
Shiyu Defense weekly: 80,000-120,000
Consistent execution over 6-8 weeks accumulates 5-8 million Dennies.
Priority 4: Polychrome Reserves
Worst-case scenario: 86,400 Polychrome (three guaranteed pities at 28,800 each). Realistic target: 40,000-60,000 Polychrome.
Version 2.5 income sources:
Daily missions: 60/day (2,520-3,360 total)
Weekly missions: 300/week (1,800-2,400 total)
Events: 800-1,500 per major event
Character stories: 300-500 per agent
Shiyu Defense monthly: 800-1,200
Exploration/achievements: 500-2,000 variable
F2P accumulation: 8,000-12,000 Polychrome. Monthly pass adds 3,000-4,000. Natural income covers one guaranteed pity with partial progress toward second.
Material Farming Optimization
Efficient farming requires strategic Battery Charge allocation. Energy system limits daily capacity.
Combat Simulation Schedule
Rotation-based farming:
Certification Seal days: Prioritize role-specific stages (Support/Anomaly/Stun)
Attribute Chip days: Focus Physical/Ether/Ice chips
Denny stages: Farm during low-priority days
W-Engine Component days: Secondary priority
Battery Charge: 240 energy/day. Combat Simulation costs 40-60 energy/run = 4-6 completions daily.
Shiyu Defense Weekly Clears
Highest-value weekly content. Floor 12 completion rewards 1,200 Polychrome/monthly reset + substantial Dennies + Master Tape fragments.
Prioritize maintaining current clear depth throughout Version 2.5 vs. building new teams—resource diversion reduces pre-farming efficiency.
Boss Material Farming
Weekly boss priorities:
Hamster Cage Passes: Required for all skill upgrades
Exuvia of Refinement: Agent-specific (Ye Shunguang needs 9)
Miasmic Elytron: Boss-specific (Ye Shunguang needs 60)
Limited weekly clears (6-8 cycles before 2.6) = finite acquisition. Complete all weekly boss content consistently vs. last-minute farming.
Drive Disc Priority
Target universal sets:
Support sets for Sunna: Energy Recharge/buff effectiveness
Anomaly sets for Aria: Anomaly Proficiency/Ether DMG
Stun sets for Nangong Yu: Daze multipliers/Physical DMG
Drive Disc farming = secondary priority after Certification Seals/Attribute Chips. Focus correct set pieces with acceptable main stats vs. perfect substats (randomized distribution makes guarantees impossible).
W-Engine and Bangboo Investment
W-Engine/Bangboo provide account-wide value persisting across updates—safer long-term investments than agent-specific materials.
W-Engines to Level Before Meta Shift
Universal W-Engines maintain utility regardless of meta:
Support W-Engines: Energy Recharge/teamwide buffs (benefit Sunna)
Anomaly W-Engines: Proficiency stats (serve Aria)
Stun W-Engines: Daze multipliers (enhance Nangong Yu)
Ye Shunguang's signature Lone Light in the Clouds: Base ATK 743, CRIT DMG 48%—stat benchmark for Physical Attack W-Engines.
Leveling cost (0-60): Basic Components x4, Reinforced x32, Specialized x30, 400,000 Dennies. Universal materials = safe pre-farming.
Universal W-Engine Safe Investments
Broadly applicable stats maintain value:
ATK%, CRIT Rate, CRIT DMG: Benefit most damage dealers
Energy Recharge: Enable faster ultimate rotations
Anomaly Proficiency: Maximize trigger frequency
Daze multipliers: Enhance crowd control
Avoid hyper-specialized W-Engines functioning only with specific agents—reduces waste risk if 2.6 introduces superior alternatives.
Bangboo Upgrades Worth Prioritizing
Priority Bangboo with:
Teamwide buff abilities: Enhance all agents
Healing/shielding: Improve survivability
Energy generation: Accelerate ultimate rotations
Elemental resistance shred: Amplify damage
Bangboo costs remain modest vs. agent development. Focus 1-2 high-utility Bangboo vs. spreading resources.
Resource Allocation Balance
Optimal prioritization:
Agent ascension to Level 60: Largest stat increases/Denny
Critical skill upgrades: Highest damage multipliers/buff values
W-Engine leveling: Guaranteed stat improvements
Drive Disc farming: After baseline agent/W-Engine development
Bangboo upgrades: Surplus resources after primary goals
Currency Management
Effective management separates successful multi-agent acquisition from resource shortages.
Dennies to Save
Per-agent complete development: 4.6-5.1 million Dennies (ascension 800k + skills 2.905M + W-Engine 400k + Drive Discs 500-800k).
Three agents: 13.8-15.3 million Dennies for complete development. Partial development (one primary full, secondary at Level 50): 8-10 million Dennies.
Version 2.5's 6-8 weeks provides 5-8 million Dennies through consistent activity. Enter 2.5 with existing reserves or accept partial development.
Polychrome Spending vs. Saving
Decision framework:
Current roster gaps: Spend if 2.5 agents fill critical deficiencies
Meta longevity: Save if 2.6 agents appear stronger
Polychrome reserves: Spend only if maintaining 28,800+ safety margin
Pity counter: Consider spending if close to guaranteed
Personal preference: Prioritize favorites over pure meta
Conservative strategy: Save maximum for 2.6's triple S-Rank rotation (higher total value vs. 2.5's dual-agent offering).
Zhao's free copy = safe investment (zero Polychrome cost). Ye Shunguang faces potential competition from future Physical agents—suggests moderate investment vs. complete optimization.
Signal Search Banner Strategy
Pity mechanics: Guaranteed S-Rank within 180 pulls. 50/50 odds first pity, guaranteed featured second pity.
Optimal strategies:
Build pity without reaching guaranteed thresholds
Avoid unwanted 5-star acquisitions near pity
Time pulls for version transitions
Leverage guaranteed pity: Plan 180-pull reserves for must-acquire
Version 2.6 Phase 1 features two simultaneous S-Rank banners (Sunna + Aria)—complex decision between splitting pulls vs. single-agent focus.

6-8 week window requires structured daily/weekly optimization.
Daily and Weekly Tasks
Daily missions: 60 Polychrome + 30,000-50,000 Dennies/day = 2,520-3,360 Polychrome + 1.26-2.1M Dennies over 42 days.
Weekly missions: 300 Polychrome/week = 1,800-2,400 total. Weekly bosses, Shiyu Defense, Hollow Zero = primary objectives.
Optimization:
Front-load Battery Charge: Complete daily farming early
Schedule weekly content: Allocate specific days for bosses/Shiyu
Event timing: Complete before expiration
Commission rotation: Prioritize high-value over low-reward
Battery Charge Efficiency
240 energy/day regeneration, 240 max capacity. Daily expenditure prevents waste from cap overflow.
Management principles:
Daily complete expenditure before reset
Priority-based allocation: Critical materials first
Overflow prevention: Monitor energy levels
Event energy costs: Account in daily planning
Consistent maximization throughout 2.5: 10,080-14,400 total energy = 168-240 Combat Simulation completions.
Event Completion Priority
Priority ranking:
Polychrome rewards: Highest value for 2.6 prep
Hamster Cage Passes: Time-gated materials
Exclusive character materials: One-time availability
Denny rewards: Large lump-sum injections
Drive Disc/W-Engine rewards: Pre-leveled equipment
2-3 major events/version: 800-1,500 Polychrome each + 500k-1M Denny-equivalent value. Complete participation contributes 2,400-4,500 Polychrome + 1.5-3M Dennies.
Last-Minute Farming Window
Final week before February 6, 2026 = last opportunity for resource accumulation.
Priorities:
Certification Seal completion: Sufficient for ≥1 agent full ascension
Attribute Chip stockpiling: Baseline quantities for skills
Denny verification: Confirm 4-5M minimum
Polychrome final count: Assess pull capacity
W-Engine components: Stockpile universal materials
Consistent farming throughout 2.5 = use final week for targeted gap-filling vs. comprehensive farming (limited timeframe prevents significant zero-baseline accumulation).
Common Pre-Farming Mistakes
Over-Investing in Soon-Powercrept Agents
Version transitions introduce power creep. Heavy investment in 2.5 agents facing direct 2.6 competition wastes resources.
Risk mitigation:
Limit investment depth: Functional levels without max optimization
Evaluate role overlap: Avoid agents directly replaced by 2.6 leaks
Prioritize universal investments: W-Engines/Bangboo maintaining value
Maintain reserves: Preserve minimum thresholds for guaranteed 2.6 capacity
Neglecting Universal Materials
Universal materials (Dennies, W-Engine components, basic chips) maintain value across updates—zero-risk pre-farming. Neglecting creates bottlenecks at 2.6 launch.
Priorities:
Denny accumulation: Required for all development
W-Engine components: Needed for signature leveling
Basic/Advanced chips: Foundation for skill progression
Drive Disc inventory: Maintain storage capacity
5+ million Dennies + complete W-Engine component sets = immediate 2.6 development upon acquisition.
Ignoring Drive Disc Inventory
Inventory capacity limits storable pieces. Excess drops auto-discard at max storage = lost pieces.
Best practices:
Regular audits: Review/discard low-value pieces weekly
Lock optimal pieces: Prevent accidental deletion
Fodder retention: Maintain upgrade material supply
Set completion tracking: Monitor progress
Emphasize correct set pieces with acceptable main stats vs. perfect substats (randomized nature makes optimal acquisition unrealistic).
Poor Stamina Allocation
Battery Charge = primary limiting factor. Inefficient allocation or regeneration waste significantly reduces accumulation.
Optimization:
Priority-based spending: Highest-value materials first
Daily complete expenditure: Prevent cap overflow waste
Event energy budgeting: Reserve for limited-time requirements
Efficiency calculation: Compare material value/energy across activities
Optimized allocation throughout 6-8 weeks gains 30-40% more materials vs. inconsistent spending/frequent waste.
